Someone knows a lightweight image library?
Author
I already took a look to SDL_Image and DevIL, but the first one requires SDL to be used and the second one is a bit huge for my needs. This is what I ask for:
-Load/Save of a few 24/32 bit image format (bmp, tga and jpg would be enough)
-Load/Save of most common high dynamic range formats
-Free for any use
I don't need image processing capabilities. I will consider simple scaling or blurring filters a plus, but nothing more. The library should be as lightweight as possible...
Thank you!

Thank you, I forgot to say that I need a c++ libray. But I won't use it with OpenGL. It is for my raytracer, to load the textures and save the renders, so I would like this library to be independent from any other library (except the tools required to handle specific formats, like i.e. the ILM lib to load HDR files).

FreeImagePlus - a C++ wrapper for FreeImage.
This is really all there is to it. Simple but powerful.
Thank you, it seems interesting! I'll give it a look :-)
Of course, I'm still open to other alternatives!
Thank you again!
corona loads pretty much anything in any format you wish for (with automatic internal format conversion if you want it).
(I slightly forgot the actual names/params of the functions, but it looks like that in general - just check the API docs)
// load some TGA and make sure it is in memory as 4-byte RGBAcorona::Image *image = corona::OpenImage("img.tga", corona::PF_R8G8B8A8);unsigned char *data = (unsigned char*)image->getPixels();delete image; // corona automatically Just Works (tm) with smart points because of this(I slightly forgot the actual names/params of the functions, but it looks like that in general - just check the API docs)

Corona would be a nice alternative, but the documentation says that it only supports a PNG and TGA as writing formats. In addition, it doesn't support HDR formats, wich are pretty much a requirement when my RT will implement some more features...
Thank you anyway!
Thank you anyway!
You can take a look at GIL which was recently added to Boost. Though I guess it's not what you would call lightweight... [smile]
GIL is really a framework for writing generic image processing code, rather than an image loading library.
It is incredibly cool though. Bit under-documented, but an amazing idea.
